Writing high-volume web APIs in Erlang with webmachine

Scripting with gen_fsm to coordinate loosely coupled back-end systems during a datastore migration.

Performance and operational comparisons between Ruby/Erlang and CouchDB/MySQL.

Talk objectives: Share our experience and results of porting a web service from Ruby to Erlang. Describe how we used Erlang to coordinate a datastore migration and the impacts of switching from CouchDB to MySQL. Discuss operations related characteristics of web services written in Erlang.
